Re: supra ventricular tachycardia symptoms

: 43 year old married mom of 3, diagnosed with svts for past 8 yrs.taking toprol xl for past 4 yrs as it seems so far to be best treatment.Still have skipped beats and an occasional flare up that requires another toprol xl.If no response must go to ER.Treatment there is based upon the location of the irregularity.Sometimes I can sense an on-coming flare-up by the feeling of pressure in my diaphragm. Does this sound weird???Has anyone else out there experienced this.I've had holter monitors, stress tests and heart card monitoring.Nothing out of the ordinary is found that can lead to another course of treatment.Problem is I can go weeks with no irregularities and then have several a day.Is anyone else out there as frustrated as I??You never know where they are going to "hit", driving, shopping, church, just talking.Would like to talk with those of you who have same experiences and your courses of treatment.Take care and God bless.
